Efforts to characterize food webs have generated two influential approaches that reduce the complexity of natural communities. The traditional approach groups individuals based on their species identity, while recently ...

Question: How does cannibalism in the host alter the evolution of a parasitoid’s oviposition strategy? Can differences in cannibalism risk between parasitized and healthy hosts alter the stage-specific foraging of parasitoids? ...

Seed dispersal is a process critical to the maintenance of tropical
forests, yet little is known about the interactions of most dispersers with their
communities. In the Dja Reserve, Cameroon, seed dispersal by the ...

We studied variation in flowering phenology, fruit and seed set, and the abundance of the pollinators
of four species of night-blooming Sonoran Desert columnar cacti for up to eight years at one site in
Mexico and one ...

Conspecific and heterospecific aboveground and belowground herbivores often occur together in nature and their interactions may determine community structure. Here we show how aboveground adults and belowground larvae of ...

Annelida represents a large and morphologically diverse group of bilaterian organisms. The recently published polychaete and leech genome sequences revealed an equally dynamic range of diversity at the genomic level. The ...

The rate of new exotic recruitment following removal of adult invaders (reinvasion pressure) influences restoration
outcomes and costs but is highly variable and poorly understood. We hypothesize that broad variation in ...

The details of the total synthesis of viridicatumtoxin B (1) are described. Initial synthetic strategies toward this intriguing tetracycline antibiotic resulted in the development of key alkylation and Lewis acid-mediated ...

Scalar population models, commonly referred to as count-based models, are based on time-series
data of population sizes and may be useful for screening-level ecological risk assessments when data for
more complex models ...

Spontaneous mutations play a central role in evolution. Despite their importance, mutation rates are some of the most elusive parameters to measure in evolutionary biology. The combination of mutation accumulation (MA) ...
